The Accelerated Aging Calculator is a useful tool designed to predict the aging process of materials under accelerated conditions. This calculator is widely used in various industries, such as pharmaceuticals, electronics, and packaging, to estimate the lifespan and durability of products. By simulating the effects of time at elevated temperatures, it helps manufacturers understand how materials will behave over extended periods under normal conditions.

## Formula of Accelerated Aging Calculator

The accelerated aging calculator uses the Arrhenius equation to predict the aging process of materials. The formula is:

Where:

- AF is the acceleration factor.
- Q10 is a constant (typically 2 for many materials).
- Ta is the accelerated aging temperature in degrees Celsius.
- Ts is the standard aging temperature in degrees Celsius.

## Example of Accelerated Aging Calculator

Let’s consider an example to illustrate how the Accelerated Aging Calculator works.

Suppose you want to determine the acceleration factor for a material tested at 60 degrees Celsius (Ta) with a standard aging temperature of 25 degrees Celsius (Ts). Assuming Q10 is 2, the calculation would be:

AF = 2^((60 – 25) / 10)

First, calculate the temperature difference: 60 – 25 = 35

Next, divide by 10: 35 / 10 = 3.5

Finally, raise Q10 to the power of 3.5: AF = 2^3.5 which is approximately 11.31

This means that the aging process at 60 degrees Celsius is approximately 11.31 times faster than at 25 degrees Celsius.

## General Terms and Values Table

Here is a table with common terms and their corresponding acceleration factors for quick reference:

Accelerated Temperature (°C) | Standard Temperature (°C) | Q10 | Acceleration Factor (AF) |
---|---|---|---|

60 | 25 | 2 | 11.31 |

70 | 25 | 2 | 22.63 |

80 | 25 | 2 | 45.26 |

90 | 25 | 2 | 90.51 |
